JOSEPH P. D'ALY, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE PROSPERITYCOMPANY, INC., OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.

AGT'UATING MECHANISM FOR PRESSING MACHINES.

Application filed August 6, 1926. Serial No. 127,528.

This invention relates to actuating mechanism for pressing machinesparticularly garment and laundry pressing machines, and has for itsobject particularly simple and 5 efficient connections by which powerfrom a reciprocating actuator is mosteffectively applied.

The invention 'consist'si'n "the novel features and in the combinationsand constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanyingdrawings in wh ch like characters represent correspondlng parts in allthe views.

Figure 1 is a side elevat1on, partly broken away, of one form ofpressing machine embodying my invention.

Figure 2 is a fragmentary rear elevat on of the intermediate lever ofthe actuating mechanism and the contiguous parts of the frame.

l designates the frame of the machine.

2 and 3 the pressing elements, the element 2 being a buck mounted on theframe 1. the element 3 a head movable toward and from the buck, and hereillustrated as carried on the front end of a yoke or lever 4, pivoted.at 5 between its ends to the frame;

6 is an intermediate lever of the actuatirig mechanism. 7 is a linkpivoted at 8 to the upper end of the upper arm of the lever 6 and at 9to the rear end of the yoke lever 4.

10 is a link pivoted at 11 to the lower arm of the lever 6 and at itslower end at 12 to the frame. The frame 1 is formed with a guide forguiding the lever in its floating movement that the power of areciproplied. As shown, the frame 1 is formed with a slot or pair ofslots 14 in opposite separated positions 15 thereof, in whlch workfollowers or rollers 16 mounted on the pivot pin 17 of the lever 6. Theslot is shown as formed with a forwardly e rtending portion18 at itslower end extendmg 1n the direction of the foldin movement of the linkof the toggle formed by the link 10 and the lower arm of the lever 6,and an upright portion extending in the same direction as the toggles 4when they approach a straight line. Owing to the arrangement of thelever 6 and the slots 14 in which the axis of saidlever moves, acomparatively rating actuator 13 is most effectively ap-,

long throw of a reciprocating actuator is converted into power or thetoggle mechanism.

The reciprocating actuator 13 is a'piston rod having its piston movablein the cylinder 19 pivoted at 20 to the frame so that it oscillatesduring the movement of the lever in the slot 14. The cylinder ispreferably double acting and inlet pipes 21 are shown as connected toopposite ends thereof. The control of the motive fluid as steam or airto and from the cylinder, forms no part of this invention and,therefore, further description is thought to be unnecessary.

In operation assuming the press is opened, or in the position indicatedin dotted lines, motive fluid is permitted to flow to the pressurethrough right end of the cylinder so that the piston rod 13 when movingoutwardly moves the oint 11 in an arc and the rollers or followers 16move rearwardly in the lower portion 18 of the slot, and during suchmovement the toggle links partly strai hten. During the remainder of thestraig tening movement, these followers or rollers 16 move in theuprightportion of the slot 14, thus givmg a boosting effect in additionto the straightening effect of the toggle. By this actuating mechanism along throw of a piston 1s converted into a powerful thrush through thepower transmitting mechanism.

I claim:

1. The combination with a supporting frame, of an actuating mechanismfor a movable element supported by the frame, the actuating mechanismcomprising a lever pivoted between its ends to the frame, connectionsbetween one arm of the lever and the movable pressing element, andconnections between the other arm of the lever and the frame, the framebeing formed with a guide for receiving a pivot of said lever wherebythe lever may be moved bodily 2. The combination with a supportingframe, of an actuating mechanism for a movable element supported by theframe, the actuating mechanism comprising a lever pivoted between itsends to the frame, connections between one arm of the lever and themovable pressing element, and connections between the other arm of thelever and the frame, the frame being formed with a guide slot forreceiving a pivot of said lever by the lever moved bodily during itspivotal movement, and a reciprocating actuator connected to the latter,the actuator be-- ing pivotally connected to the frame to oscillateduring the pivotal movement of the lever and the movement of the leveralong the slot. r

3. The combination with a supporting frame, of an actuating mechanismfor a movable element supported by the frame, the actuating mechanismcomprising a lever pivoted between its ends to the frame, a link pivotedat one end to one arm of the lever, and connected at its other end tothe movable element, a link pivoted at one end to the other arm of saidlever and at its other end to the frame, the lever being mounted in theframe to shift bodily relatively thereto, and a reciprocating actuatorconnected to the lever, the actuator being also pivoted so that itoscillates during the movement of the lever along the slot.

4. The combination with a supporting frame, of an actuating mechanismfor a ZIIOV able element supported by the frame, the actuating mechanismcomprising a lever pivoted between its ends to the frame, a link pivotedat one end to one arm of the lever, and connected at its other end tothe movable element, a second link pivoted to the other arm of saidlever and forming a toggle therewith to the frame, the frame beingformed-with a slot for receiving the pivot of the lever, and areciprocating actuator connected to the lever, the actuator being alsopivoted so that it oscillates during ,the movement of the lever alongthe slot, said slot having one end portion extending in the direction ofthe folding movement of the toggle formed by the second link and saidlever, and another portion arranged at an angle to the former portionand extending in a direction parallel to that assumed by the lever whenthe links connected thereto approach a straight line.

5. The combination with a supporting frame, of an actuating mechanismfor a movable element supported by the frame, the actuating mechanismcomprising a double toggle arranged to move into a straight line when instraightened position,

said double toggle including an intermediesasm ate lever pivoted betweenits ends, one arm of the lever forming a link of one toggle, and theother arm, the link of the other tog gle, the lever being mounted in theframe to shift endwise during the straightening and folding of thetoggle and a reciprocating and oscillating actuator connected to thelever.

6. The combination with a supporting frame, of an actuating mechanismfor a movable element su ported by the frame, the actuating meclianismcomprising double toggle arranged to move into a straight line when instraightened position, said double toggle including an intermediatelever pivoted between its ends, one arm of the lever forming a link ofone toggle, and the other arm a link of the other toggle, the leverbeing mounted to float during the straightening and folding of thetoggle, the frame being formed with a slot for receiving the pivot ofthe lever to permit the floating movement of the lever and areciprocating and oscillating actuator connected to the lever.

7. The combination with a supporting frame, of an actuating mechanismfor a movable element supported by the frame,

the actuating mechanism comprising adouble toggle arranged to move intoa stralght line when in straightened position, said double toggleincluding an intermediate lever pivoted between its ends, one arm of thelever forming a link of one toggle, and the other arm a link of theother toggle, the lever being mounted to float during the straighteningand folding of the toggle, the frame being formed with a slot forreceiving the pivot of the lever and ermit the floating movement of thelever, t e slot being formed with a portion at one end extending in thedirection of the folding movement of one of the toggles and anotherportion extending in the direction of the straightened toggles and areciprocating and oscillating actuator connected to the lever.

In testimony whereof, I have hereunto signed my name, at Syracuse, inthe county of Unondaga, and in the State of New York, this 12th day ofJuly, 1926.
